Abstract: One of the crucial problems to be tackled relating to adsorbed natural gas storage is the detrimental effect of adsorption heat on storage capacity. Based on the practical charge process, a relatively simple one-dimension, non-adiabatic model was established and thereafter numerically solved in order to evaluate several possible approaches to the problem. For an adsorption cylinder of about 50 L, the simulations revealed that a 10-minute charge with the adsorbent bed dissipating heat naturally gives a charge efficiency of 0.76, which is higher than that for an adiabatic charge only by 0.03. It was also shown that cooling the inlet gas is not a feasible way to enhance the charge performance, while external-recycle cooling or charging at elevated pressures can effectively compensate for the performance loss.
